No video on the player

Test one affected file in the newer Media Player or Movies & TV app first; if video works there, repair Windows Media Player Legacy, but if it also remains audio-only, check the video codec and graphics driver.

1. Identify Windows and isolate the player

1. Press Windows key + R.
2. Type winver, then select OK. Note whether it says Windows 10 or Windows 11.
3. Right-click a video file and select Open with.
4. Choose Media Player or Movies & TV.
   • If neither appears, open Microsoft Store and search for Media Player by Microsoft Corporation.
   • The current Media Player is built into Windows 11 and is available for Windows 10 through Microsoft Store.^1^

2. If video works in the other app

The files and system video output are working, so repair Windows Media Player Legacy:

1. Open Windows Media Player Legacy.
2. Press Ctrl + M to display its menu.
3. Select Tools → Advanced → Restore Media Library.
4. Reopen the player and test a video.

If that does not help:

1. Close Windows Media Player.
2. Press Windows key + R.
3. Enter: %LOCALAPPDATA%\Microsoft\Media Player\
4. Delete the files inside that folder, but do not delete the folder itself.
5. Restart Windows Media Player and test again.^2^

Deleting these database files rebuilds the player’s library; it does not delete the actual videos.

3. If every app plays audio without video

Check which video codec the files require:

1. In Windows Media Player Legacy, press Ctrl + M.
2. Select Help → About Windows Media Player.
3. Select Technical Support Information. A browser page will list installed codecs.
4. While a video is loaded, right-click it in the library, select Properties → File, and note the Video codec.

Windows can add support through Microsoft Store extensions for formats including MPEG-2, HEVC/H.265, VP9, AV1, and Web Media.^3^ Install only the extension matching the reported codec.

Avoid general-purpose codec packs from download sites. Microsoft warns that some packs can introduce compatibility problems or system corruption; use Microsoft Store extensions or the codec provider’s official site.^3^

The older “Download codecs automatically” procedure applies specifically to Windows Media Player 11. Use it only if Help → About Windows Media Player confirms version 11:

1. Select Tools → Options → Player.
2. Enable Download codecs automatically.
3. Select OK, replay the file, and accept the codec installation prompt.^4^

4. If codecs are present but all videos are still blank

Update the display driver:

1. Open Start → Settings → Windows Update → Check for updates and install available updates.
2. Obtain the latest graphics driver from the PC or graphics-card manufacturer.
3. Restart Windows—use Restart, not Shut down—and retest.

Microsoft identifies current graphics drivers as necessary for video playback. If that fails, open Command Prompt as administrator and run:

sfc /scannow

Restart after the scan completes. Microsoft also recommends the Windows Media Player troubleshooter and, as a final repair, removing and reinstalling Media Features through Control Panel → Programs → Turn Windows features on or off.^2^
